Abstract

The present invention is applicable to the technical field of icing wind tunnel measurement, and provides a device and method for measuring ice shape in an icing wind tunnel test. The measuring device includes a support assembly and a metal cutter; the support assembly includes a horizontal support platform, and the The horizontal support platform is used to support the metal cutter, and the metal cutter can move on the horizontal support platform; a travel switch is arranged on the horizontal support platform, and the metal cutter moves on the horizontal support platform When moving upward, the travel switch can be touched; it also includes a spray head, which can spray quick-freezing agent outward, and when the metal cutter touches the travel switch, the spray head is turned on; when the When the metal cutter does not touch the travel switch, close the nozzle. In the present invention, whether the nozzle is opened or not is controlled by whether the metal cutter touches the stroke switch or not. Therefore, the degree of automation is high, and there is no need to manually control whether the nozzle is opened or not.

Description

technical field [0001] The invention belongs to the technical field of icing wind tunnel measurement, and in particular relates to an ice shape measuring device and method for icing wind tunnel tests. Background technique [0002] During the flight of the aircraft in the cloud layer, its wings are prone to icing physical phenomenon in the low temperature environment. When the large area of ​​the wing freezes during the flight of the aircraft, the aerodynamic shape of the surface of the wing will be seriously changed, the aerodynamic performance will be destroyed, the flight resistance will increase, the lift will decrease, and in severe cases, the aircraft will stall. In the history of aviation, there have been more than a thousand flight accidents due to aircraft icing. Therefore, researchers need to better understand the icing characteristics of aircraft in low-temperature flight environments, and then need to complete relevant experimental tests in icing wind tunnels. ...
